He received the Telecommunication Engineering Degree and the Electronics Engineering Degree from Universitat Politècnica de Catalunya, Barcelona, Catalunya, Spain, and the Politecnico di Torino, Torino, Italy, respectively, both in 1999, under the Double Degree Socrates-Erasmus Scholarship Program of the European Community, and the Ph.D. in Communication Systems from Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in 2004.

He is a Research Professor of the Institució Catalana de Recerca i Estudis Avançats (ICREA) hosted at the Department of Information and Communication Technologies, Universitat Pompeu Fabra, Barcelona, Spain, and an Adjunct Researcher at the Department of Engineering, University of Cambridge, United Kingdom, where he is also a Visiting Fellow of Trinity Hall. He is also a visitor at the Centre de Recerca Matemàtica.

From August 1998 to March 1999, he conducted his Final Research Project at the Center for Wireless Communications and Signal Processing Research, at the New Jersey Institute of Technology, Newark, NJ. He was with Telecom Italia Labs, Torino, Italy, from November 1999 to June 2000. From September 2000 to May 2001, he was with the European Space Agency (ESA), Noordwijk, The Netherlands. During his doctoral studies, from 2001 to 2004, he was a Research and Teaching assistant at the Mobile Communications Department, Institut Eurécom, Sophia-Antipolis, France. From June 2003 to July 2004 he was a visiting scholar at the Communications Theory Lab at EPFL. Since September 2004 until December 2006 he was a Research Fellow at the , University of South Australia, Mawson Lakes, Australia. From January 2007 unitl September 2011 he has been a Lecturer at the Signal Processing and Communications Laboratory, Department of Engineering, University of Cambridge, Cambridge, United Kingdom.
